Environmental artists and climbers, Martin Hill and Philippa Jones live and work in Wanaka, but have used the world as their canvas. They conceived of the Fine Line Project, 25 years ago. It consists of 12 ephemeral environmental sculptures, created on site in remote locations, including Iceland, Madagascar, Vanuatu, Canada and Antarctica. Each creation is connected to the next by a symbolic line drawn around the earth and is featured in their book Fine Line. Their endeavour has been showcased in the BBC4 series Nature and Us: A History Through Art, presented by art historian James Fox.
